I have a 10" powered bazooka tube (built-in amp) and it has started cutting out. It will work fine for 5 seconds and cut out for 5 seconds. I can't figure out what's going on. Jiggling the plug doesn't help. Does anyone know if this is a common problem and/or and easy fix? I know it's a long shot. I honestly know next to nothing about subs and their wiring/installation. Any advice? I bought it new 2 years ago.

I assume you have a big fuse inline with the power wire going to the battery? Check that connection and see if that is the cause. I had the plastic housing break on my main fuse and short out/heat up. The sub would work for a short period, cut out, then come back when it wanted to.

Thanks y'all, Ill look into these. Any other ideas? I don't think it's getting hot. It starts going in and out as soon as I turn the radio on.

The guy at best buy (who installed the sub 2 years ago) told me that the light will stay green if there are no internal problems, but will turn red if there are. That's all he would do for me, wouldn't even look at the sub...

Pretty typical for a place like Best Buy. They're more interested in the initial sale rather than helping down the road. It's probably more of a not knowing standpoint rather than being rude. Those type places only know how to box things up and send them back to the manufacturer. Not how to actually troubleshoot and service them.

Since you've checked the big fuse on the main power wire. I'm thinking this is head unit related if you aren't getting a red light, we can eliminate it being and amp, ground, or power wire problem. Could be the connection to the back of the head unit, or the Co-Ax cable connecting the head unit to the speaker. You may try at least looking at that connection or changing the Co-Ax cable.
